-2

Step-by-step explanation:

y = mx+b (B is y-int)

y = 4^x-2

-2 is clearly replacing the b (y-int) meaning b, the y-int, is -2

[tex]y = {4}^{x} - 2 \\ for \: y \: intercept \: x \: s \\ is \: 0 \\ y = {4}^{0} - 2 \\ y = 1 - 2 \\ y = - 1 \\ [/tex]

Answer:

The percentage change in volume from cylinder A to cylinder B is 50% volume increased by 50% option (C) is correct.

What is a cylinder?

In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.

We know the formula for the volume of the cylinder is given by:

We have r = 10 inches and h = 5 inches

V = 500π cubic inches

Percent change in volume from cylinder A to cylinder B:

= 50%

Thus, the percentage change in volume from cylinder A to cylinder B is 50% volume increased by 50% option (C) is correct.

A triangle is a 2-D shape that has 3 sides and angles. The area of the triangle below is 27 square units

A triangle is a 2-D shape that has 3 sides and angles

In order to determine the area of the shape, we will determine the area of the square circumscribing it first;

Area of the square = 10 * 9 =90 square units

Find the area of the two right triangles

Area of the right triangles = 0.5(10 * 9) + 0.5(9 * 4)

Area of the right triangles = 45 + 18

Area of the right triangles = 63 square units

Take the difference

Area of the given triangle  = 90 - 63 = 27 square units

Hence the area of the triangle below is 27 square units

Marcella won't be able to win the competition because the length of the rope is less than 162 feet.

How to find the sides of a right angle triangle?

The situation forms a right angle triangle.

The kite released rope is the hypotenuse side of the triangle formed.

The opposite side of the triangle is the height of the kite from the ground.

Therefore,

sin 28 = opposite / hypotenuse

sin 28 = 75 / h

h = 75 / sin 28

h = 75 / 0.46947156278

h = 159.754085116

h ≈ 160 feet

Therefore, she won't be able to win the competition because the length of the rope is less than 162 feet.

The y-intercept is 3.75, and the equation of the line of best fit is

y = 1.5x + 3.75, and after 13 months, 23 matches could be won.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

Part A:

As we can see in the graph, the line crosses the y-axis at a certain point between 3 and 4.5.

So the y-intercept lies between 3 and 4.5

We can take the middle of these two values to get the approximate value of the y-intercept.

b = (3+4.5)/2 = 3.75

We know the line of the best fit is:

y = mx + b

y = mx + 3.75

b is the y-intercept and m is the slope of a line

Plug the point (9, 18) in the equation to get the value of m:

18 = 9m + 3.75

m = 1.5

y = 1.5x + 3.75

Plug x = 13 months in the above equation:

y = 1.5(13) + 3.75

y = 23.25 ≈ 23 number of matches that could be won

Thus, the y-intercept is 3.75, and the equation of the line of best fit is

y = 1.5x + 3.75, and after 13 months, 23 matches could be won.

The length of the band in terms of π is given by the expression:

L = 40mm + π*10mm

Remember that for a circle of diameter D, the circumference is:

C = π*D.

Now, if you look at the image, you can see that the length of the band will be equal to 4 times the diameter of the pencils (one time for each side). Plus 4 times one-fourth of the circumference of each pencil (for the four corners).

because the diameter is 10mm, the length of the band will be:

L = 4*10mm + 4*(π*10mm/4)

L = 40mm + π*10mm

This is the length of the band in terms of π.

Given expression: 4x - 7

To determine a numerical value of the provided expression, when x = 4, simply substitute the value of x into the expression and simplify it using the order of operations (PEMDAS). Work has been shown below.

The PEMDAS stands for:

According to the PEMDAS, it is required to simplify the expression using multiplication (M in PEMDAS) firsthand, as there are no parentheses (P in PEMDAS) and exponents (E in PEMDAS). Thus, we get the following:

Please refer to underlined text for simplification of that expression.

Clearly, we can see that division (D in PEMDAS) and addition (A in PEMDAS) is not occurring in the expression. Therefore, we will need to subtract the two terms (16 and 7). Thus, we get the following simplified term:

Therefore, the value of 4x - 7, when x = 4, is 9.

Step-by-step explanation:

Let's start with the first inequality, [tex]y < -x^{2}+x[/tex]. To check which points satisfy this inequality, we can substitute the x- and y-coordinates and see if they satisfy the inequality.

Once again, we can repeat this for the second inequality (but this time, we only need to check the points that satisfy the first inequality).

Therefore, the answer is (A) (0, -1).

The compound interest when $7300 when interest is compounded semi annually is $2482.70.

The compound interest when $7300 when interest is compounded monthly is $1972.73.

An investment earns compound interest when both the amount invested and the interest accrued increases in value at predetermined time intervals.

The formula to represent compound interest is :

FV - amount invested

FV = P (1 + r)^nm

a. 7300 x [1 + (0.1/2)]^(3 x 2) = 9782.70

Compound interest = 9782.70 = 7300 = $2482.70

b. 7300 x [1 + (0.08/12)]^(12 x 3) = 9272.73

Answer:

y = -x - 5

Step-by-step explanation:

The general structure of a line in slope-intercept form is:

y = mx + b

In this form, "m" represents the slope and "b" represents the y-intercept.

Since you have been given the slope and y-intercept, you can substitute these values into the equation to find the answer.

m = -1                  

b = -5

y = mx + b

y = (-1)x + (-5)

y = -x - 5

Answer:

y = -x -5

Step-by-step explanation:

We can use y = mx + c to find the equation of the line.

Here,

m ⇒ slope of the line

c ⇒ y - intercept

They have already given that,

m ⇒ -1

c ⇒ -5

So, now we can write the equation of the line like this.

To write the equation of the line you can replace m and c with -1 & -5 respectively.

Let us write now.

y = m x + c

y = -1x - 5

Step-by-step explanation:

The attached image can give you an idea of what you get when a plane perpendicular to the base of a cone intersects the vertex of the cone.

In the problem statement here, we assume a double-napped cone with no defined base. That means the lines of intersection with the sides of the cone will meet at the vertex point and extend indefinitely in either direction.

The intersection is a pair of intersecting lines.

Answer:

y = 130

Step-by-step explanation:

given that y varies directly with x and z then the equation relating them is

y = kxz ← k is the constant of variation

to find k use the condition y = 150 when x = 2.5 and z = 12 , then

150 = k × 2.5 × 12 = 30k ( divide both sides by 30 )

5 = k

y = 5xz ← equation of variation

when x = 4 and z = 6.5 , then

y = 5 × 4 × 6.5 = 20 × 6.5 = 130
